Stress hormones such as norepinephrine have been shown to cause upregulation of cytokines such as Interleukin 6 and 8, which are proangiogenic and support tumour progression. Coupled with genetic and environmental factors, stress appears to play a role in melanoma formation and progression.

Is melanoma caused by stress?

Stress and Skin Cancer

However, stress may also play a role, as it causes the body to produce unstable oxygen molecules called free radicals. Those can increase inflammation and damage your skin's DNA, leading to mutations and, possibly, skin cancer.
